His fully erect member was quivering in the air. People standing around where staring at this strange sight. Dustin never noticed. He got behind the lioness and plunged in, swiftly jackhammering her. As he was screwing her, the crowd watched in awe as tawny fur sprouted all over Dustin's body. His hair turned black and grew longer as new hair sprouted from around his neck and down his chest. As he came the, fur was complete.
Ty was looking on in amusement. Dustin looked like a human with lion fur and a mane, but Dustin wasn't done yet. Lions mate multiple times.
Just as Dustin's cock was softening, it started to stiffen again. Unable to control himself, Dustin plunged in again. As he jackhammered away, a tail started to grow. As it reached its final length, fur quickly started to cover it ending with a tuft of black fur on the end. Dustin's ears took on a more rounded appearance and slid to the top of his head as he finally came.
After a moment's pause, Dustin was full erect and ready to go again. A rather large crowd had started to gather, including most of the class. Some students were laughing, some were just standing in awe.
As Dustin started to mate the lioness a third time, his muzzle started to push out as his teeth changed into razor sharp fangs and he came a third time.
Dustin's cock stiffened for the fourth time, but the lioness had had enough. She slinked back to the shadows where she was dozing before.
"I didn't expect this to happen," Ty thought. Dustin stood there in the center of the Lion's den looking like someone with a fur suit on, except for his fully erect cock.
